Embodiment 1

[0087] Present embodiment provides a kind of forage sorghum and silage corn mixed planting method, comprises the steps:

[0088] (1) Fine ground preparation

[0089] In mid-October, a piece of newly reclaimed desert sandy soil was selected as a test site, and the soil was loosened in the vertical and horizontal directions with a rotary tiller, plowed 35-40cm deep, and leveled with a harrow. Combined with fermented and decomposed farmyard manure 4000kg / mu for site preparation, enough winter water;

[0090] (2) Moisture conservation and fertilization

[0091] In the first ten days of April, apply chemical fertilizer as base fertilizer (the base fertilizer is a mixture of 20kg / mu of urea, 10kg / mu of phosphorus diamine, and 8kg / mu of potassium sulfate), and form a ridge after leveling with rakes. The ridge width is 120-130cm, and the ridge height is 18- 20cm, ridge spacing 35-40cm, double rows per ridge;

[0092] (3) Lay mulch and drip irrigation tape

[0093] Adopt under-mulc...

Embodiment 2

[0107] Present embodiment provides a kind of forage sorghum and silage corn mixed planting method, and its steps are as follows:

[0108] (1) Fine ground preparation

[0109] In mid-October, a newly reclaimed desert sandy soil was also selected as a test site, and the soil was loosened in the vertical and horizontal directions with a rotary tiller, and the soil was plowed 35-40 cm deep, leveled with rakes, and combined with land preparation and fertilization. Fermented and decomposed farmyard manure 4500kg / mu, filled with winter water;

[0110] (2) Moisture conservation and fertilization

[0111] In the first ten days of April, apply chemical fertilizer as base fertilizer (the base fertilizer is a mixture of 22kg / mu of urea, 12kg / mu of phosphorus diamine, and 10kg / mu of potassium sulfate), and form a ridge after leveling with rakes. The ridge width is 120-130cm, and the ridge height is 18- 20cm, ridge spacing 35-40cm, double rows per ridge;

Abstract

The invention belongs to the technical field of crop planting and relates to a forage sorghum and silage corn mixed planting method and application thereof. The forage sorghum and silage corn mixed planting method includes the steps of fine land preparing, soil moisture conservation and fertilizer application, mulch and dripper tape laying, seeding, field management and harvesting. The forage sorghum and silage corn mixed planting method helps implement advantage complementation between varieties and improve crop biomass and quality; water-saving effect is significant. The forage sorghum and silage corn mixed planting method helps solve the problem that an arid or semiarid region has feed shortage, single planting mode and low producing capacity of flooding water; the contradiction of water resource shortage of the arid or semiarid regions can be relieved; the forage sorghum and silage corn mixed planting method is importantly practical to the adjustment and optimization of husbandry structures.

Description

technical field [0001] The invention belongs to the technical field of crop planting, and in particular relates to a mixed planting method of forage sorghum and silage corn and its application. Background technique [0002] With the adjustment of my country's agricultural and animal husbandry industry structure, grain-saving animal husbandry has developed rapidly. However, the grassland area in our country has been drastically reduced due to degradation or destruction of the ecological environment, and the productivity is low, which is difficult to meet the development of animal husbandry. In 2016, the state successively issued related policies such as "grain to fodder", which promoted the development of food crop production to forage crop production, and forage production faced better policy opportunities. [0003] The sandy soil of the newly reclaimed desert is a newly reclaimed oasis that has expanded from the old oasis to the desert in recent decades, and its soil type ...
